The Radeon RX 7900 XTX is the most advanced graphics card from AMD that promises to deliver superior performance for gaming and video editing. It features a powerful engine, GDDR6 memory, and support for DirectX 12, making it an attractive choice for those who need to edit high-definition videos. But is the 7900 XTX good enough for serious video editing applications?
To answer this question we took a closer look at the 7900 XTX’s specs and compared them to other cards in its class. It turns out the 7900 XTX excels in terms of both raw power and graphical capability, making it more than capable of handling complex video projects with ease and a bit overkill for 1080p. The card also delivers sharp visuals thanks to its enhanced Anti-Aliasing technology and support for up to four displays simultaneously.

As seen in the table above, the 7900 XTX improves over what AMD has already constructed to deliver impeccable performances. The new GPU has 24GB of GDDR6 VRAM as opposed to the 16GB the previous GPU had. This gives the unit more space to move big sets of data, which will help a lot for high-end video editing.
Pugetsystems.com has created a deep analysis of how the RX 7900 XTX behaves in video editing when compared with other top-end GPUs, such as the RTX 4090, 4080, and even previous AMD GPUS, like the RX 6900 XT.
In that analysis we can see, in summary, how the RX 7900 XTX outperforms the 6900 XT easily by around 30% in their DaVinci Resolve Studio benchmark, and 22% in the Adobe Premiere Pro benchmark. In both comparisons, the 7900 XTX delivers results much akin to Nvidia’s.
Do you need a powerful graphics card for video editing?
Depending on the editing software you use and the type of video you edit, you may benefit from the different features and specifications of powerful graphics cards. For example, if you’re working with a 4K or higher resolution video, or need faster rendering times, you may want to invest in a high-end graphics card with more VRAM, memory bandwidth, and cores.
How much GPU is enough for video editing?
If you’re interested in editing 1080p videos, a 4GB VRAM will suffice. Although, it is advisable to use a GPU with at least 6GB of VRAM for 4K footage, but 8GB would be best.
